Understand that electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
Recall the general trend of electronegativity on the periodic table: it increases from left to right across a period and decreases from top to bottom within a group.
Identify the positions of the given elements on the periodic table: Nitrogen (N) and Oxygen (O) are in period 2, Chlorine (Cl) is in period 3, and Fluorine (F) is in period 2 but further to the right than Nitrogen and Oxygen.
Compare the elements based on their positions: since electronegativity increases across a period and decreases down a group, Fluorine, being in period 2 and group 17 (halogens), has the highest electronegativity among the options.
Conclude that Fluorine (F) is the most electronegative element among the choices given.
